SPECIFICATION forming part of Letters Patent No. 446,311, dated February10, 1891.

Application filed December 24, 1889. Serial No. 334,903. (No model.)

T all whom t may concern:

Be it known that I, HENRY L. WHITMAN, of

the cit-y of St. Louis,in the State of Missouri,"

have invented a certain new and useful Improvement in Ealing-Presses, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming part of thisspecification.

My invention relates to certain improvement-s inpresses for baling hay,straw, excelsior, and the like.; and my invention consists in featuresof` novelty hereinafter fully described, and pointed out in the claims.

Figure I is a top Aor plan view of my improved press. Fig. II is a sideelevation of the same. Fig. III is an enlarged detail top view of thepower end of the press. Fig. IV is a similar view showing the parts in adifferent position. Fig. IVL is a horizontal section taken on the lineIV IV, Fig. VI. Fig.

IVb is a detail vertical section taken on line IV.b IV), Fig. VI. Fig. Vis a similar view to Figs. III and IV, showing the parts in stillanother position. Fig. VI is an end view of the power end ot' the press.Fig. VII is a detail view showing the manner of securing the jointedbeam thatJ forms a connection between the baling end and power end ofthe press. Fig. VIII is a side elevation of the saine. Fig. IX is avertical transverse section taken on line IX IX,Fig. VIII, and lookingtowardthe power end of the press. Fig. X is a det-ail horizontal sectionot' the baling end of the press, taken on line X X, Fig. XI. Fig. XI isa vertical transverse section taken `on line XI XI, Fig. X, and lookingtoward the power end of the press, the traverser being-omitted. Fig. XIIis a detail vertical longitudinal section showing the por tion of t-hepress at the feed-opening and showing also the traverser. Fig. XIII is adetail side elevation showing the friction device at the delivery end ofthe press, and Fig. XIV is an end view of same. l*

Referring to the drawings, I represents the baling end, and 2 the powerend of the press. These parts are connected by a beam or sill 3,overwhich the animals pass as the press is operated. This beam is made intwo parts,

so that the press can be divided in transportation, and it is connectedvat the joint by means of a lower plate 4 and an upper plate 5. (SeeFigs. VII, VIII, and IX.) The plates are secured to the inner portion ofthe beam by bolts 6 and to the. outer portion. of the beam by bolts 7.The plates are also preferably flanged, as shown in Fig. IX. By re'-moving the. bolts G it will be seen that the beam may be disjointed t-odisconnect the ends of the press, as stated. For the purpose of givingadditional strength to the joint I secure rods S to the outer portion ofthe beam, these rods' being preferably connected to the outer portion ofthe beam by means ot' bolts 9 and clips lO. The inner ends of the boltspass through eyes 1I of a strap 12,secured to the upper platev 5 by onepair of the bolts 7. The eyes Il project beyond the sides of the beam,and by tightening on the nuts of these rods it will be seen that-additional strength to the joint will be afforded. The central portionof the beam is provided with a standiard 13, from'which extends arod 14to the power end of the press and a rod 15 to the baling end of thepress. These rods are shown in Figs. I and II. The rod 15 is con-`nected to the standard at 16, (see Fig. IX,) and the rod 14 is connectedto the standard at 17.- (See Fig. IX.) By the use of theseconnecting-rods the power end and baling end of the press are morefirmly secured or attached together. secured to the baling-chamber ofthe press by means of a cross-head 18, (see Figs. I, X,-

XI, and XII,) and the outer end of the rod 14 is connected to the powerend of the press by means ot a yoke 19. (See Figs. I, II, and VI.)

15 is a lat strap,.(see Figs. I and IX,) secured at one end by means ot'abolt 15 to the inclined projection or arm 151 of the standard 13, andat the other end is'secured by means of a bolt. l5d to the cross-head18. This strap is merely to protectthe rod 15 from beingl struck by theanimals feet as the animals pass around in operating the press.

20 represents thelever or sweep of the press located on a vertical shaft21, which passes through a frame 22. (See Fig.VI.) The sweep and frameare removed in Figs. III, IV,

IOO

and V. Vithin the frame 22 on the vshaft 2l. is across-head Thiscross-head 23 is provided with an upwardly-extending neck 24, (see FigIVb,) which passes through the yoke 19, through the upper part of theframe 22, and through the sweep-head. 'The sweephead is provided withgrooves to receive lugs 24 on the neck 24, as shown in Figs. IV and IV",and thus the sweep and cross-head 23 are connected together permanentlyand made to revolve with eachother.

23n 4represents a cap on the sweep, through which set-screws 23b passinto the neck 24, and by tightening on these set-screws the bearingbetween the neck (which is conical) and the sweep may be tightened.

25 25u represent arms provided with a hub 26, (see dotted lines, Fig.VL) through which the central shaft or rod 21 passes. This hub 1sloosely mounted on the shaft, and one of the arms 25 has automaticengagement with vthe cross-head 23 by means of a block 27, pivoted tothe end of one of the arms by means ot' a pin 28. The block is providedat its free end with a triction-roller29, (see Figs. III and IV,) whichis engaged alternately bythe ends of the crossdhead 23. This end oftheblock is also provided with a pin 30, fitting in a slot 3l, formed inthe end of thearm carryingthe block. This pin and slotlimit the'swinging movement of the block. The free end of the block is held toits inner position (shown in Fig. IV) by means of aspri ng 32, surrounding abolt or rod S23-,which passes through a rib or flange 34 onthe arm. (See Figs. III, IV, and IVu.) IVhen the block is in theposition shown in Fig. IV, which is its inner position, thefriction-roller 29 is in the path of the cross-head 23. and it will A beseen that as the sweep and crosshead are turned the engagement of thecrosshead with the friction-roller 29 causes a oonnection between thecross-head and the arm 25 which causes the arm to be turned on thecentral pin 21. The pin 30, beneath the arm 25, is provided with afriotion-roller 35, (see Fig. VI,) which comes against a fixed cam 36(see Figs. IV and VI) at the proper time, and forces the free end of theblock, with the frictionroller 29, outwardly, and causes thedisengagement of the cross-head with the arm 25, A The arm 25, as thetraverser moves forward, bears against a friction-roller 37 onthe outerend of the pitman 3S of the press, as shown in Figs. III and IV, andthus it will be seen that as the arms 25 25 are turned by the sweep and.cross-head, as described, the pitman, which ot' course carries thetraverser of the press at its inner end,

` will be forced forward until the roller 35 rebound by the expansion ofthe compressed material, which may be assisted, if desired, by means ofa spring-rod 39. (See Fig. II.) The outer end of the pitman is pivotedby means of a link- 4 0 to t-he timber or sill-piece 3 at 41, and as thetraverser advances and recedes this link 40 turns ou the pivot 41, andit will be seen that as the traverser reaches the limit lof its forwardmovement that the poiutof bearing between the arm 25 and the pitman willapproach the center 2l of the power, thus transferring speed into powenThe pivot 41 may be connected with the central shaft 2l by means of aplate 42.

43 represents a track secured to the timber 3, and upon which bears afriction-roller 44, secured to the end of the link 40. (See Fig. VI.)

45 representsthe traverser, secured to the inner end of the pitman 38.

To the upper rear end of the traverser is hinged a iiap or plate 4G at47. This flap is connected by means of a `chain or cord 48 to the hopper49 ofV the press. At the joint 47 the flap is provided with a shoulder50,which, when the flap is in its lower or horizontal position, bearsagainst ashoulder 5l on the traverser. These shoulders hold the iiap inits horizontal positioinas shown by dotted lines, Fig. XII. Thelfunction of the iiap is to close the bottom of the hopper 49 when theplunger or traverser is in its inner position, and

thus prevent the hay or stuff from falling i into the baling-chamberbehind the traverser.

It will be understood thatin operating' these baling-'presses the hay orstuft being baled is thrown into the hopper regardless ot whether theplunger is in its rear or its inner position, and were it not for thetraverser being long enough to close the bottom of the hopper when inits inner position the stuff would t'all into the baling-chamber behindthe traverser, which, ot` course, would not be desirable. The object ofhinging the flap to the traverser and connecting it by a chain to thehopper is to cause it to be folded up, as shown by full lines, Fig. XII,when in its outer position, so as not to be in the Way of thedraft-animals in their circuitous route in operating the press. If theflap were not hinged and compelled to fold up as the plunger reached thelimit ot its outer movement, it will be understood that the connectionbetween the baling end of the press and the power end would have to beas much longer than it is where the Hap is hinged than the iiap is long,so that by hinging the Hap and folding it the length of the -press isconsiderably lessened. As the trav` erser moves inward the flap 46 foldsdown for the purpose stated, and then as the traverser recedes it isturned up again in the position shown in full lines, Fig. XII. As theplunger recedes it comes against friction-blocks 5.2, pivoted at 53 tothe sides of `the press, these blocks being made adjustable in or out bymeans of'hinged rods 54, (see Figs. X and XL) which are connected attheir tops by a rod 55, made in two parts `having right IOO IIO

and left threads on their adjacent ends, where th'ey are connected by asleeve 5G. Between the heads on the outer end of the connectingrod andthe upper ends ot' the rods 54 are springs 57. By turning the sleeve 56in the proper direction it will be seen that the friction-blocks will beshoved in or out, and by the use of the springs 57 a yielding frictionbetween the traverser and the blocks is obtained.

The sides of the delivery end of the press are provided with adjustableplates 60. (See Figs. XIII and XIV.) By adjusting these plates in or outthe friction between them and the material being pressed is controlledfor the purpose of regulating the density of the bales. The top andbottom plates are adjusted by vertical screw-threaded rods 7 O, providedwith wheels 62 working therein and having hubs 6l bearing on boxes 6l,secured to the upper timbers of the baling-chamber. The lower ends ofthe rods7O have heads 7l bearing against boxes 7 2, secured to the lowertimbers of the baling-chamber, and it will be seen that by tightening onthe wheels 62A the top and bottom plates of the baling-chamber will becontracted vertically. Surrounding the shafts between the boxes 6l and72 are sleeves G3, having eccentrics 63 working in yokes 63h, secured tothe plates 60. Springs 64 are placed between the eccentrics and the.

plates GO. It will thus be seen that by turning the sleeves with theeccentrics the plates GO will be moved in or ont, and by the use of thesprings 64 a yielding elastic friction is produced between the stuffbeing baled and the plates. The sleeves are provided with sockets 7 3 toreceive a rod or lever by which the sleeves are turned.
